Royal Ascot was developed on the old Milnerton Racecourse, and an important feature of the development is the Milnerton Racecourse Nature Reserve which was originally the central open area inside the track. This is now one of the last remaining areas of Cape Flats Sand Fynbos with elements of West Coast Strandveld. The 18ha reserve has over 240 plant species, of which 12 are rare and endangered.
